Key role of China and its agriculture in global sustainable phosphorus management
Growing global demand for food leads to increased pressure on phosphorus (P), a finite and dwindling resource. China is the largest producer and consumer of P fertilizer in the world. A mass balance…
Aggregated indices for trends in eutrophication of different types of fresh water in the Netherlands
As in many European countries, eutrophication of surface waters is a key problem in the Netherlands, caused by high concentrations of nitrogen (N) and phosphorus (P). For implementation of the EU…
Crop yield response to soil fertility and N, P, K inputs in different environments: Testing and improving the QUEFTS model
Global food production strongly depends on availability of nutrients. Assessment of future global phosphorus (P) fertilizer demand in interaction with nitrogen (N) and potassium (K) fertilizers under…
Mariculture: significant and expanding cause of coastal nutrient enrichment
Mariculture (marine aquaculture) generates nutrient waste either through the excretion by the reared organisms, or through direct enrichment by, or remineralization of, externally applied feed inputs…
The global nitrogen cycle in the twenty-first century
Global nitrogen fixation contributes 413 Tg of reactive nitrogen (Nr) to terrestrial and marine ecosystems annually of which anthropogenic activities are responsible for half, 210 Tg N. The majority…
European scenarios for exposure of soil organisms to pesticides
Standardised exposure scenarios play an important role in European pesticide authorisation procedures (each scenario is a combination of climate, weather and crop data to be used in exposure models)…
Hindcasts and Future Projections of Global Inland and Coastal Nitrogen and Phosphorus Loads Due to Finfish Aquaculture
A global model is used to calculate feed and nutrient budgets for freshwater and marine omnivorous and carnivorous aquacultural finfish production. The model uses national production data for the…
Costs and Benefits of Nitrogen for Europe and Implications for Mitigation
Cost-benefit analysis can be used to provide guidance for emerging policy priorities in reducing nitrogen (N) pollution. The results support the priority for further reduction in NH 3 and NO x…
A new report commissioned by the United Nations Environment Programme (UNEP) highlights how humans have massively altered the natural flows of nitrogen, phosphorus and other nutrients. While this has…
The EU and the World Health Organization apply a drinking water standard for nitrate in drinking water of 50 milligrams per litre. The risks to human health posed by nitrate in drinking water have…
